52. Reporting cheating What proportion of students are willing to report cheating by other students? A student project put this question to an SRS of 172 undergraduates at a large university: “You witness two students cheating on a quiz. Do you go to the professor?" The Minitab output below shows the results of a significance test and a 95% confidence interval based on the survey data.16 Session Test and Cl for One Proportion Test of p - 0.15 va p not - 0.15 Sample X N Sample p 1 951 CI Z-Value P-Value 19 172 0.110465 (0.063619, 0.157312) -1.45 0.146 (a) Define the parameter of interest. (b) Check that the conditions for performing the signifi- cance test are met in this case. (c) Interpret the P-value in context. (d) Do these data give convincing evidence that the ac- tual population proportion differs from 0.15? Justify your answer with appropriate evidence.
